Distributor advance springs

Are You purchasing bearings for a known good crank, or??? If the crank You plan to use doesn't check out, You will be buying undersize ones if it gets re-ground, or a replacement that's been done the same.
Well, my dad told me he’s pretty sure the crank is gonna need turned down .010 or .020 but he knows a machinist here in town who will give me a good deal to have it turned. So I’ll prolly take the car to my brothers next weekend and pull the motor out and check the crank to determine what the best next step is
